Is this Worcester, Prattware...its a copy of Chinese work...

A few hundred years ago Chinese fashion was all the rage! English and continental producers tried to copy the superior chinese goods-what goes around comes around so we shouldnt really complain about Chinese copies of our goods today.
I am not sure what this cup is, I am fairly certain it is English (and with no damage!), is it Prattware? This cup is very well glazed, maybe someone out there may know....I would be glad of any suggestions.
